Ruzgaila

Cf. Rozgáila (see). Maybe a compound surname from *Rus-pity. Sand's Russian origin is unclear - for him, cf. lit. rùsas „kas kūrena ugnį“, rusénti „pamažu degti, smilkti; lėtai bėgti, eiti, tursenti“ (LKŽ XI 1014), rùsinti „kurstyti, deginti; judinti, krutinti“ ¹. Unfortunately, see Bargáila.
